Hi thanks for sticking with me. The caps @ c101-103 are open. The standby cap next to D123 is showing 1075ohms but only when I put the negative lead of the meter on the positive of the capacitor and positve of the meter on the negative. If I connect positive to positive and neg to neg then I get open circuit. Does this all look good if so I will try to source a fuse today.

I’d recon with a bad main board too. However, first you need to fix that PSU.

Cheers guys, will go and get a fuse and report back. Someone else locally had the same issue with a power spike and it took out everything that was connected to the TV as well. However all the peripheral devices that were connected to this survived.

It's alive :-)

My local electronics store is closed (Maplins same store as what Tandy used to be in the USA). Looked up local TV repair guys, found a local one that was only a short walk and asked if he would sell me a fuse. Went round and picked it up for £2 and all working. Havent tried TV tuner but HDMI works, so attached my android streaming box and all good. Do get some flashing of the standby light when I switch it on (not sure if this is normal dont think it used to do that) maybe it is seeing a problem with the tv tuner anyone know the error sequence on these?

Thanks to everyone here for the advice of checking the various parts so I was confident that the fuse I knew had gone was perhaps the only issue.

Some tv's will flash the stby led after the power is pressed while it is initializing and waiting for backlights to come on, likely happened before and you did'nt notice.
good to here its fixed.

A close lightning strike with the tuner connected to an outside antenna likely took out the tuner module. it usually sees micro volts of signal not giga volts from a lightning strike

I think you got very lucky to only lose a fuse and the tuner. Usually any TV that I get that’s got hit by lightning, I have to replace the main board, because the main ic got damaged.

The house next door cannot be lived in due to the damage took over 3 hours to put the fire out they have been told may not even spend Christmas in there! So double tripple lucky. Roof top aerial got vaporised I think as that is nowhere to be seen the downlead was just a frazzled section of plastic blown off the wall.
